HUM'IDIF'IER.

Application filed January It is customary to providein hot air fur? naces aii humidiiying' means comprising a receptacle into which water may be introduced from the exterior of the furnace and from which this water may evarwrateinto the air current. As these receptacles are constructed at the present time, however, there no way to -cl osethe opening through which the water evaporates into the air current and accordingly water beinp' poured into the receptacle very often spiashes over in appreciable quantity into the interior of the furnace where it produces-obvious detrimental results. Theprinciple object of my invention is to provide humidifying means of this type free from this objection. In the drawings accompanying-this application and forming a partthereoi? I have shown, for purposes 01: illustration, three forms which my invention may assume. In these drawings:

Figure I is a fragmentary side elevation of a furnace embodying thefirst 'otthese three illustrative forms,

Figure 2' is a fragmentary section on the line 22 of Figural, l 1

Figure 3 is a fragmentary section on the line of FigureQ,

Figures 4 and dare liragmentary sections similar to Figure 3 showing optional meth ods 01 supporting the cover on the recep tacle,

Figure 6 is a view similar to Figure 1 showing the second of the three alternative forms,

Figure 7 Figure 6,

Figure 8 is ifragmentary horizontal section above the top of the receptacle showingthe third ofthe three alternative forms with the cover in one position, while pp Figure 9 is a view similar to Figure 8 showing the cover in alternative position,

The embodiment of my invention disclosed in Figures 1 through 3 comprises a receptacle 11 supported by the base plate 12 of the furnace 13 in position extending through and closing an aperture 14 in the furnace wall 15, and provided with an open top 16 divided by the furnace wall into an outer opening 17 through which water may be inserted into the receptacle 11 and an inner opening 18 through which water may evaporate into the air current within the furnace wall 15. Mounted upon this receptacle 11, by means of trunnions 19 pivotally supportis a section on the line 77 of a; 192-5. seriaixm. 4,334.

edin arcuateprojections 20 011 the side walls 21 of the receptacle 11,9is a cover 22 comprising an' outer portion 23 arranged to overlie and close the outer opening 1'7 and an inner portion 24 arranged to overlie and close the inner opening 18 but disposed at an angle tothe outer portion 23 so that when the outer portion 23 is imposition closing; the outer opening; 17 the inner portion 24 is raised from the inneropening 18 asshown in i'ulllincs in Figure Q and when the inner portion- 24 is in position closing the inner opening 18 the outer portion 23 is raised from the outer opening 17 as shown in dotted lines in Figure 2.

In Figures 4 and 5 I have shown optional forms of supporting the cover irom the receptacle, the form in Figure 4 comprising trunnions 25 carried by the cover 26 and pivot-ally supported in arcuate projections 27 extending extcriorly of the side walls :28

oi the receptacle 29,and the form in Figure 5 comprising trunnions 30 carried by the cover 31 and pivotal-1y supporiedin recesses 32 formed directly on the side walls 33 of the receptacle 34.

In the embodiment-oi my invention shown in Figures 6 and? the receptacle 35 is again supported upon the base plate 1'2 01 the fur nace 13 and projecting through the opening 14 in the furnace side wall l'owith itsopen top 36 similarly divided into an outer opening 37 for the insertion of the water and an inner opening 38 fortheyevaporation of the water into the air current. Inthis :i orm', however, a cover 39 is reciprocably mounted upon the receptacle 35 by means of lower guides 40 and upperzguides 41 entendinginwardly fromthe'two end walls 42 of the recept-acle 35 below and abovethe edges43 of between an outer posit-ion closing the outer opening 37 as shown in full lines in Figure 7 and an inner position closing the inner opening38 as shown in dotted lines in Figure 7. In this construction reciprocation of the cover 39 is facilitated by the upturned forward edge 44 and excess outward movement is deterred by the upturned inner cover edge 45.

It will be obvious, however, that I may omit the upper guides 41 and also that I may omit either or both of the upturned edges 44 and 45.

In the form of my invention disclosed in Figures 8 and 9 the receptacle 46 is supthe cover 39, and this cover is reciprocahle ported and positioned in the same manner and provided with the open top 4;? divided by the furnace wall d8 into the inner opening 49 and the outer opening 50. In this form, however, the receptacle 46 is provided with an ear 51 arranged to pivotally support a horizontally swinging cover 52 comprising an outer part 53 arranged to overlie and close the outer opening 50 and an inner part 54L arranged to overlie and close the inner opening 49 but disposed, in relationto the outer part 53 in such manner that when the outer part5?) is in the position shown in Figure 8 exposing the outer opening 50 the inner part 54 is in position closing the inner opening 49, and when the inner part 54 is in the position shown in Figure 9 exposing the inner opening 49 the outer part 53 is in position closing the outer opening 50.

It will be apparent that each of the three embodiments of my invention herein shown provides a closure for the inner receptacle opening and therefore provides means to prevent water splashing into the interior of the furnace. It will also be apparent that in each of the forms of my invention herein illustrated this cover is connected to and correlated with the cover closing the outer opening in such manner that movement of the outer cover to expose the outer opening automatically closes the inner opening. It will therefore be obvious that the forms of my invention herein disclosed accomplish the principal object of my invention.

herein shown and described may be variously changed and modified without departing from the spirit of my invention or sacrificing the advantages thereof. It will therefore be understood that this disclosure is illustrative only and that my invention is not limited thereto.

I claim:

1. Means. for humidifying the air of a hot air furnace, comprising a receptacle pro vided with an outer opening arranged to permit the insertion of water into said receptacle from the exterior of said furnace, and an inner opening arranged to permit the vaporization of such water into the air within said furnace. and a unitary cover arranged to close said openings alternately to thus prevent water being inserted into said receptacle through said outer opening splashing through said inner opening into the interior of. said furnace.

2. Means for humidifying the. air of a hot air furnace, comprising an open top receptacle having its open top divided by the furnace wall into an outer opening lying outside said furnace wall and arranged to permit the insertion of water into said receptacle from the exterior of said furnace, and an inner opening lying inside said furnace wall and arranged to permit the vaporization of such water into the air within said furnace, and a unitary cover arranged to close said openings alternately to thus prevent water being inserted into said receptacle through said outer opening splashing through said inner opening into the interior of said furnace.

3. Means for humidifying the air of a hot air furnace, comprising a receptacle provided with an outer opening arranged to permit the insertion of water into said re-- ceptacle from the exterior of said furnace, and an inner opening arranged to permit the vaporization of such water into the air within said furnace, and a unitary cover of a size to close either of said openings and slidably mounted to close said openings alternately to thus prevent water being inserted into said receptacle through said outer opening splashing through said inner opening into the interior of'said furnace.

4. Means for humidifying the air of a hot air furnace comprising an open top receptacle having its open top divided by the furnace wall into an outer opening lying outside said furnace wall and arranged to permit the insertion of water into said receptacle from the exterior of said furnace,

and an inner opening lying inside said furv nace wall and arranged to permit the vaporization of such water into the air within said furnace, and a unitary cover of a size to close either of said openings and slidably mounted to close said openings alternately to thus prevent Water being inserted into said receptacle through said outer opening splashing through said inner opening into the interior of said furnace.

In testimony whereof, I hereunto aflix my signature.
